Okay, let's clarify a couple of things: 1. this wasn't "necessary" in the sense that OMPI won't build without the change. It was "desirable" in terms of eliminating some long-standing warnings coming from those areas due to changes in automake in anticipation of a compatibility break when automake 2.0 is released. In other words, these are "deprecation" warnings.
2. I have advised Matthias and Bert about the situation before, but they were concerned about the proposed change being installed in their code base because of potential backward compatibility issues. However, we are requiring automake 1.12.2 as a minimum level, and this is backward compatible to that level (I checked on the web site, and verified on my machines). This is why I allowed it into 1.8.2 at this time. It silenced the warnings, and given our minimum AM requirement, was compatible. I wouldn't necessarily advise the VT folks to ingest it as I believe they are trying to stay compatible to older versions of AM (same situation for libevent), but that's up to them.
